I want to come back to this circle

I was doing really well for the longest time. Managed to stay sober through a wedding, with others drinking around me, offering me drinks, party drugs, all that. Was doing well, exercising, eating well. Went through massive stress and fell off the wagon. I’m not used to feeling this shitty- but it used to be my usual, until recently I drank this heavily everyday. I want to go back to being healthy again. My anxiety is insane, vertigo, and I didn’t even have any fun! I’m dreading tomorrow as I’ve been recovering for days and still feel terrible. It’s Saturday and I’m already worried about being tired for work on Monday :( I’m bloated as hell and want to get back on the wagon
